V WARM-AIR nEArIn'e nners'rnn Application filed December 29,4927. Seria1"No. 243, 229.

Myinvention pertains to a register adapted to control circulation through an air passage such as the room outlet of an air heating conduit.

The object of my invention has been to produce a structure of the character described made entirely of stamped parts so as to be lighter in weight and more economical in large production, while attractive in appearance and convenient to assemble with quick detachability of certain units. a

It is to be realized that the scope ofmy invention comprehends many equivalent constructions. The showing of the drawing :the particular description are merely speclfic exemplifications of a plurality of mechanical embodiments andarrangements.

Adverting to the drawing: Figure 1 is a front elevation of a reglster embodying my invention.

Figure 2 is a side elevation thereof.

Figure 3 is a fragmentary rear elevation of the upper construction on the line-33 of Fig. 2 showing hinges and other details.

Figure 4 is an enlarged vertical section on line H of Figure 3.

Figure 5 is a similar View showingcertain parts in a partially detached pos1t1on.

Figure 6 is a correspondingly enlarged vertical section on line 66 of Figure 3 and with a damper in its open position.

Figure 7 is a View corresponding to Figure 6 taken on line 77 of Figure 3.

A main frame 1, quadrilateral as shown, is

intended to be fitted in a wall of a room and has a forward face slightly receding in an upward direction and defin ng a quadrilateral opening 2, the lower margin of which is defined by a rearwardly recessed and inversely bent flange 3 comprising a lower substantially horizontal section provided'with a pair of slots 4 and comprising an upper horizontal section 5 to serve the function of a ledge, as will be hereinafter explained. The upper -'margin of the opening 2 is also defined by an inversely bent flange including a horizontal section 6, a downwardly extending section 7 and another horizontally ext-ending section 8 which is fashioned with a plurality of spaced recesses 9.

. vide crosswise extending recesse's,- as shown in Figure 2; the purpose of which will be here- Y inafter disclosed." The bottom-ofthe grille isprovided with aplurality oftongues 14 corresponding in-number and arrangement to 1 the dispositionof the slots land adapted to be;

inserted theretl'irough, as shown i'nFigujre 2, whereby movabl'y and detachably to connect Theuppermargin 15 of the rille isgfiat and zthelowerend of the'grille with thefra'nie 1 is secured, as, for instance, by spot-welds 16 to a section- 17 ofa shutter and grille carry ing member including also a rearwardly projecting-and resilientsection 18 which in conjunction withlthe section 17 determines the L shjap'eof saidlnember. Y =The' fiange 18 fashioned atintervalswith upwardlyoffset spherical projections 19, corresponding-in number andsp ac'ing to the recesses Q and adaptedto be sprung into interfitted relation therewith, as shown in Figu're 4, or forcibly withdrawn as shown in Figure5. At four points along the flange 18v and between the section 17 an'cl fofsets I 19, hinge sockets 20 are struck: outin -a manner wellknown to: the stamping art: 'A

sheet metal shutter 21 intended alternative lyto' lie against the inside of thegrille 1 0 ,-'has two portions of its upp'er. edge curled at 22- to formaepair of'coacting hinge socketsL' ,It will be observedthatthehinge sockets 22 are curved inversely to the four hingesockets 20 and adapted tobe locked one between :each

spaced pair of'hinge sockets 20 inwhic'h positioii they'areheld' by hinge pins 23, as will be readilyunderstoodby those skillful in the art; Thelower end24 of the shutter is curved forwardly and is-ad'apted to occupy a 1 position partially underneath the flange 13 whereby to "improve the closure at that-point-when .the shutter occupies the position in which'it isillustr'ated inFigure 1.3 The middle of the shutter ispro'vided at itsatop with an aperture 25, shown in Fi ures. A handle26 pro jects rearwardly through the middle top with a handle projecting forwardly both opening in the grille and passing throughthe through said shutter and structure.
